Abstract
Provided is a video decoding method including: obtaining affine parameter group candidates of a current block based on whether adjacent blocks of the current block are decoded; determining an affine parameter group of the current block from among the affine parameter group candidates, according to affine parameter information of the current block; and reconstructing the current block, based on one or more affine parameters included in the affine parameter group.
Claims15
A video decoding method comprising:
- obtaining affine parameter group candidates of a current block based on whether adjacent blocks of the current block are decoded;
- determining an affine parameter group of the current block from among the affine parameter group candidates, according to affine parameter information of the current block;
- and
- reconstructing the current block, based on one or more affine parameters included in the affine parameter group.
A video decoding apparatus comprising a processor configured to obtain affine parameter group candidates of a current block based on whether adjacent blocks of the current block are decoded, determine an affine parameter group of the current block from among the affine parameter group candidates, according to affine parameter information of the current block, and reconstruct the current block, based on one or more affine parameters included in the affine parameter group.
A video encoding method comprising:
- determining affine parameter group candidates of a current block based on whether adjacent blocks of the current block are decoded;
- determining an optimum affine parameter group for predicting the current block;
- and
- determining affine parameter information of the current block indicating the optimum affine parameter group of the current block.
